SOLE OR HEEL FASTENING.

SPECIFICATION forming part of Letters Patent No. 329,952, dated November10, 1885.

Application filed July 30, 1885.

T all whom it may concern:

Beit known that I, FEEEEORN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Sole and Heel Fastenings, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part of this specification, inexplaining its nature.

The invention consists in a fastening for securing the soles and heelsto the insoles of boots and shoes, having a screw-threaded shank andatapering point, made, preferably, from wire, as hereinafter described.

Referring to the drawings, Figure l representsin elevation wire squarein cross-section, which I subsequently provide with screwthreads bytwisting. Fig. 2 represents in elevation the wire after it has beentwisted to form threads. Fig. 3 shows in elevation a modified form ofthe wire before twisting or turning, and Fig. 4 shows Vthe same twisted.Fig. 5 shows a nail-blank cut from the wire shown in Fig. 2. Fig. 6shows it provided with a point formed by two bevels. Fig. 7 represents anail with the point eccentrically arranged. Fig. 8 shows a nail withscrewthreads of a quicker pitch than those of Fig. 3o 6. Fig. 9 is aview of a nail having a round point.

In making the fastening I prefer to use square-sectioned wire, or wirehaving the section represented in Fig. l, and to submit this wire to aturning action, whereby the corners are made to form screw-threads, asrepresented in Fig. 2. These threads are of a comparatively slow pitch.The nail is completed by being severed from the screw-threaded wire, andhaving a clinching-point formed thereon, preferably shaped asrepresented in Fig. 6, which preferably is provided by cutting away thelower corners and sections of the blank to form the two beveled surfacesa c; but of 45 course I do not confine myself to this shape Serial No.173,022.

or point, but may use a point of any other character or form.

In operation, to use the fastening, I may or may not form a hole by anawl for its reception; but if usedas a heel-fastening it will bedesirable to first form a hole for it. rlihe fastening, upon beingdriven, will revolve or turn as it is forced through the stock, and itspoint, coming in contact with an iron or metal surface, will be turnedback and clinched in the stock.

This form of heel and sole fastening is very desirable for many reasons,and especially because it has all the advantages of a screwfastening,and yet may be driven into place instead of screwed. It may also,because of its peculiar shape, be driven straighter, and from having aclinching-point it is securely held or fastened in place after it hasbeen driven.

Of course, it is obvious that the pitch of the thread of the fasteningmust not be so inclined or quick that the fastening will not turn uponbeing driven, and it is of course obvious that the fastening can be usedwithout a point, although for general use it will be found desirable toprovide it with one.

It will be seen that a nail of this character is especially desirable asa sole-fastening, because, while having all the advantages of a screwfor holding the outsole, it does not re- 7 5 quire to be screwed intothe insole, as it has a clinching-point which holds it rmly thereinwhatever the thickness of the sole.

Having thus fully described myinvention, I claim and desire to secure byLetters Patent of 8O the United States- A shoe-nail formed from squareor substantially squarerod or blank, twisted to provide threads ofcomparatively slow pitch, and provided with a clinching-point,substantially as 85 described.
